DEVICE FOR REGULATING- THE `CLOSING OF DOORS.

Application filed April 30, 1327. Serial No. 187,'761.

This `invention relates to a i double door i closing regulating means, and refers more particularly to a device adapted to hold one door partially open until the other door has closed. i

The primary object of myinvention is to provide a simple device to besecuredto the central part of the framework above the doors, and adapted to hold one of the doors open far enough to allow the second door to by-pass and close, the second door, upon closing, actuating the device to release the first doorto close upon the second.

Advantages of my invention are its simplicity, which insures eiiiciency of operation, and its inexpensive, yet permanent constructon, there beingno springs or other parts necessitating frequent or even occasional repairs.

Other objects and advantages as well as those mentioned 'may be observed in the course of the following detailed description, taken in connection with the annexed drawings forming a part thereof and in which:

Figure l shows a side elevation of the invention partly in section, with the fall member in the raised position to allow both doors to close.

Figure 2 shows a side elevation with the fall member in lowered position so that the right door will stop against the front edge of the right side of the fall member.

Figure 3 is a top or plan view of my invention.

Figure 4 is a side elevation of the sheath or stationary member. 4

Figure 5 is a front elevation of the fall member in the position shown in Figure 1.

Figure 6 is a front elevation of the fall member as shown in F igure 2.

Figure 7 is a top or plan View of my invention in place showing its operation in combination with the door movement.

F igure 8 is an enlarged View of the central portion of Figure 7 to more clearly show detail. i

Continuing the description, my device is comprised of two prinoipal members, a stationary sheath comprised of a central upper strip 5 and ends 6--6 having extensions 12-12 adapted to receive a pin 8, and a fall member comprised of a straight portion 3, having circumferential measurements identical with extensions 12-12, and adapted to receive pin 8. This reception hinges the fall member to thesheath. The fall member also has a forward extension, divided as shown into strips l and 2, in acute angular rela tionship one to the other, a vertical wall supporting and dividing the strips. A contrivance 7, is secured in the straight part of the fall member, and isadapted to work through a hole 13, in the sheath. v

The sheath is secured in the head of the door frame above the doors in such a manner as to allow the doors free movement into and out of the frame, the latter being hollowed outto allowrfree upward movement of the contrivance 7.

My device will block the door 14 until the door lO has reached the dotted line ll, at which time the fall member will have raised sulticiently to allow the door 14 to clear the forward edge of the strip l, of the fall member. In Figures 5 and 6 the dotted line ;13-90 indicates the top of the doors. The letters a-a`show the point on the fall member where the strip 2 begins to incline. The front edge of the fall member is curved to neet the door 14 with a minimum of friction. Numeral 15 designates a rabbet adapted to close the crack between the two doors, and 16 and 10% metal plates on doors lt and 10 respectively to avoid wear upon or against the wooden structure of the doors. 18-48 represent door hinges.

I designed and developed this device to overcome the difliculty attendant upon the closing of double doors in the proper sequence. Much inconvenience is caused by the wrong door closing first, but that is impossible with my device in attachment..

Door 10, being the door to be closed first,

i in closing, strikes under the 'forward edge of strip 2, passing forward and elevatng the fall member on the hinge formed by the y association of the sheath and the fall member through the agency of the securing pin 8.

When it reaches the point indicated by dotted line 11, see F igures 2and 7, the strip 1, whose forward edge has engaged the door 14 against the plate 16, is raised, allowing door ll to pass inward to the france. This door cannot close therefore until door 10 has closed enough to release the fall member. The latter drops by its own weight on the hinge pin, into controlling position, when the doors are opened, the contrivance 7 serving as a check to limit the drop or fall. V

I wish to make it understood that I do not wish to limit myself to the exact form of conlast mentiened plane to struction as shown, except as comes within the scope and meaning of` the following claims. e i i i I claim:

1. In a device of the character described, in conbination with a pair of doors, of a sleath set in the door frame above the pointof meeting of the doors, of a fall member adapted to be lnitably hinged in said sheath, and to extend in a horizontal plane from said sheath, said fell member having the body thereof divided into plane surfaces extending in angular relationehi one to the other, from the pivotal pointo the fall member in the sheath to the advanced end of the fall member, one of said planes in said member adapted to apply the advanced edge thereof against one of the doors, the other plane adapted to slidably engag e the other door, the movement of the last Inentioned door adapted to elevate the release the first plane from the first door. i i

2; In a door eloeing regulating device, a.

fall member in a limited hinged attachment in a sheath above a pair of doors, said sheath positioned in the door treme, said fall member being divided into two angularly related planes, a brace between said planes, one of the planes adapted to abut against one of the doors until the other plane is lifted by the other door, wheren the first plane is released from the filet door.

3. In a devce of the character described, in eombnaton with a pair of doors, oi a sheath ada ted to be Secured in the central rtion of t e door hame, of a fall member in the sheath, said fall memberhaving a longitudinal angular division into two plane euri faces, one of said planes adapted to check the movement of one door` until the other plane surface is engaed by the other door to lift both planes an release the first plane from the first door. i i

In testimony whereof I have signed my name` to this specification.
